Row of grenades — time to run (12)
I believe the answer is:
disagreement
'row' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's an association between them I don't understand?
'grenades time to run' is the wordplay.
'to run' indicates anagramming the letters.
'grenades'+'time'='grenadestime'
'grenadestime' with letters rearranged gives 'DISAGREEMENT'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for disagreement that I've seen before include "Argument" , "Quarrel" , "Contretemps" , "Lack of consensus" , "dispute" .)
